“That said, one of the things that seems like an odd omission is any kind of āmediumā mode. Maybe Iām misreading the specs, but I see two low-power modes that last a really long time and two high-power modes which last a bit less than an hour. As someone who night hikes quite a bit, neither seems particularly useful to me- I need something that gives off a decent bit of light, but can also sustain that for a reasonably long period of time so that Iām not burning through batteries.Iām not sure any of those modes”
+ 1Ā There is a middle range, 50-100 lumens, which is useful for night hiking and some camp tasks, and does not drain the battery so quickly.Ā My Fenix HL50 has a medium setting of 60 lumens, which is perfectly adequate for most night hiking and lasts for a rated 9 hours 45 minutes.Ā It also has a high setting of 170 lumens, which lasts for a rated 3 hours.Ā I have yet to find a need for it.Ā Its low setting of 4 lumens lasts for a rated 150 hours;Ā it is adequate for nighttime excursions and inside the tent tasks except for reading.Ā Lest this be misconstrued as a pitch for Fenix, there are many other excellent headlamps on the market that perform in the same range.Ā The takeaway point is that the yawning lumen gap in the middle range would seem to eliminate the TH20 as a serious backcountry headlamp, IMO.
